Carmine "Vermillion"

Carmine is the true protagonist of the anime, appearing in both chapters as the partner and friend to two different female characters (who could be considered the heroines of their respective episodes). Along with the countless thousands of dragons who came to the human world, he is a defender of humanity against the scourge of demons. Of course, his initial arrival wasn't greeted well and he faced a difficult beginning.

When he first arrived in the human world in the God Chapter, he was still an egg in his mother's arms. The Japanese SDF shot and killed his mother (like they did with the other 21 dragons who came to Hokkaido), who left the egg in the care of a human girl, Riko. His egg had already cracked open during the ruckus, so the first he got to see after being born is his mother's bloody end.
